SpletThe rst thing we need to check is that T(f~) 2C[0;1] for all f~ 2C[0;1]. This is true because the above antiderivative is de ned for all x 2[0;1], and is continuous on [0;1] (by the Fundamental Theorem of Calculus). To check that T is a linear transformation, we check addition and scalar multipli-cation: Splet首先， S (x) 为分段三次多项式，设 S (x)=a_jx^3+b_jx^2+c_jx+d_j\quad (j=0,1,...n-1) ,其中 a_j,b_j,c_j,d_j 为待定系数，所以 S (x) 有4n个未知数。 约束条件为 S (x),S' (x),S'' (x) 连续
